Calculate the osmostic pressure associated with 50.0 g of an enzyme of molecular weight 98,000 g/mol in water to give 2600 mL of solution at 30.0 degree C. A) 0.00064 atm B) 0.0022 atm C) 0.0026 atm D) 0.0048 atm E) 0.003 atm How long will it take to electroplate a flute with 28.3 g of silver at a constant current of 2.0 amps using AgNO_3? Assume 100% efficiency. A) 211 minutes B) 422 minutes C) 844 minutes D) 105 minutes What is the effect of decreasing the temperature on an endothermic reaction? (k is the rate constant and K_eq is the equilibrium constant.) A) k decreases and K_eq increases B) k decreases and K_eq decreases C) k increases and K_eq decreases D) k increases and K_eq increases E) not enough info to decide on K_eq If the same mass of each of the following metals experiences the same heat loss, which metal will have had the largest temperature change?
